5 Claims.

The present invention relates to mechanism for receiving ingots and delivering them to rolling mills and the like.

Various mechanisms for handling heated ingots and delivering them to rolling mills have been heretofore suggested and placed in operation in steel plants. Ingots which are delivered to mills to be rolled into various shapes, such as rails, bars, and the like, are, as is well-known in highly heated condition. They are furthermore not entirely homogeneous throughout, that portion of the ingot which is uppermost in the ingot mold as the ingot solidifies being most likely to contain piping and segregations of impurities. The mill operator, knowing this, may desire to deliver the ingot to the rolling mill with that end foremost which is more free from defects, that is, the end which is at the bottom of the ingot mold when the ingot is solidifying. On the other hand, it may be more desirable in certain instances to deliver the ingot to the rolling mill with its upper or more defective end foremost.

The present invention contemplates a mechanism for receiving heated ingots and delivering them with the desired end foremost, whether this end be that which may be designated the top, or the generally more defective end, or the bottom or generally more perfect end. It contemplates a device which may either be placed upon a rolling mill floor in permanent relationship to a rolling mill or which may be mounted upon a truck or car so as to be transportable from place to place. When so movably mounted, it may likewise comprise a means for transporting heated ingots from a soaking pit to the rolling mill. 7

Essentially the invention comprises a base upon which an ingot may be placed on end and means positioned above the base and movable with respect thereto, for laterally engaging the ingot and tilting or swinging the same into a position permitting its discharge, either by gravity or by power driven mechanism, onto a rolling mill table or the like. The end of the ingot which first moves from the apparatus and is first presented to the rolling mill may be determined by the operator after consideration of the nature of the rolling operation to be performed, etc.

In adapting the invention to various situations and in the handling of various products, numerous changes may be made in the design and arrangement of its parts. In the accompanying drawings, a preferred form of the invention is disclosed by way of example, the ingot receiving and delivering means being shown mounted upon a truck so that it likewise comprises an ingot transporting means.

In the drawings:

Figure 1 is a top plan view of the mechanism mounted upon a truck or car;

Figure 2 is a side elevation of the same;

Figure 3 is a section on line 3-3 of Figure 2, showing an ingot positioned vertically in the apparatus;

Figures 4, 5, and 6 are views similar to Figure 3 either direction, this means being generally indicated at 11. The base itself may be formed in various ways but very conveniently may be constructed in the specific manner shown in the drawings, having parallel side frames or pedestals 12 and 13 respectively which are secured together by rods such as 14, 15, and 16.

Rods l4 and 15, which are horizontally'disposed and are also parallel to each other, support the ends of curved bars 17 which, taken together, constitute the actual operative portion 35 of the base,'that is, the portion upon which the lower end of the ingot rests. The upper surface of each bar 17 is curved about a horizontally disposed axis, which is indicated at 18, so that the upper and effective surface of the base is cylindrical,-having this axis as its center. A portion of each side of each bar 17 is cut away as at 19 so that slots are left between the bars for the circulation of air, thus preventing overheating of the supporting base by'the very highly heated ingot resting thereon.

The movable member 11 comprises a box-like structure, preferably a one-piece casting having trunnions rotatably supported in hearings in pedestals 12' and 13' the side frame members 12 and 13 respectively. Member 11 may be given a swinging movement in either direction of rotation about the axis of its trunnions, which axis is coincident with the Xis 18 above referred to, from the position in which it is shown in Figure 3 to the several positions shown respectively in Figures 4, 5, and 6. Rollers are indicated at 29, these rollers being mounted upon member 11 and projecting through suitably aligned apertures in the side walls there- I projecting upwardly from 100 of so that, when member 11 is tilted in either direction, one side of the ingot is engaged by one set of rollers, there being four rollers in each set. Upon rod 16 is mounted a further roller 20 over which the ingot may pass on its way to a rolling mill table or the like.

Any suitable'means may be chosen for tilting the member 11, but, where possible, I prefer to utilize an electric motor, such as indicated at 21, connected to one of the trunnions through reduction gearing contained within. casing 22, pinion 23,

and gear 24 mounted upon the trunnion. The motor 21 is reversible, and hence member 11 may be swung about its axis of rotation readily in either direction. It it locked in any of the positions to which it is adjusted by means of the motor by the reduction gearing contained in the casing 22, this gearing being irreversible. The truck body upon which the ingot receiving and delivering device is mounted is intended to be driven byan electric motor, and such a motor is indicated'at 25. The details of construction of. thegtruck frame and the driving connection between motor 25 and the wheels of the truck are not illustrated as they form no part of the present invention.

Means is provided for positively driving the rollers 29 to facilitate dischargepf the ingot from the-member 11. This means is illustrated in Fig: ures 7 and S, where it will be seen that the two rollers 29 shown (Figure 8) are fixed on shafts 30 and that theseshaits pass through the sidewall of member 11, being rotatably supported therein,

and carry at their ends pinions 31. There are thus four shafts 30 and four pinions 31, and the teeth of each of these pinions 31 mesh with the teeth of a large spur gear 32 integral with a sleeve 33, which sleeve is rotatably mounted upon the elongated trunnion34 of member 11. Sleeve 33 is in, turn rotatably supported in trunnion support 12, and italso has rotatably mounted onits outer end a worm wheel 35-which may be operatively connected to or disconnected from sleeve 33 by means of a-magnetic clutch 36. Meshing with the teeth.

of. worm wheel;35 are those of a worm 37 fixed on a shaft 38 and adapted to be driven in either direction of rotation by areversible electric motor 39. a

Assuming,the magne tic clutch 36 to beenergized,- motor 39 will be thenoperativelyconnected to all of the eight rollers 29, and rotation of the shaft 38- causes simultaneous rotation of all of the rollers. Thus, by energizingrthe magnetic clutch 36 and motor 39, the rollers may be actuated to assist in the discharge of the ingot from member 11, whether the ingot be in an inclinedor horizontal position If it is desired to discharge aningot along a -relatively steeply inclinedpath, it'may be unnecessary to actuate the rollers; upon which the ingot isresting by power .means, and hence the magnetic clutch 36 is not caused to operatively connect worm 35 and sleeve 3,3.v W herever the ingot is to be horizontally discharged, however, andin some instances where it is to be discharged along an inclined path, the rollerdriving mechanism is employed. Whenever the ingotis in process of being tilted,'the magnetic clutch 36 is inoperative, thus permitting rotation of sleeve 33 relatively to worm wheel 35 and permitting gear 32 to rotate on its axis. As a result, pinions 31 and the rollers 29 to which they are connected do not rotate during the tilting movement of member 11 but are only called into action when clutch.36 and motor 39 are energized.

The two motors shown may be conveniently controlled by means of reversing switches so that the operator may eifect the discharge of an ingot, either horizontally or along an inclined path, very quickly and may discharge the ingot with either the'large or small end foremost as desired.
